Vendor-hosted web conferencing is usually licensed as a service based on one of three pricing models: a fixed cost per user per minute, a monthly or annual flat fee allowing unlimited use with a fixed maximum capacity per session, or a sliding rate fee based on the number of allowed meeting hosts and per-session participants (number of "seats").
To watch a class, click on the class image. This will take you to the AOL online classes lounge. From there, you may have three options: To watch a class that is on replay, you do not need to do anything. The class will automatically play. To watch a class that is live, click Enter Class. Click Watch Live or Restart Class if the class has ...
Members of a brainstorming session will write one CRC card for each relevant class/object of their design. The card is partitioned into three areas: [1] [2] On top of the card, the class name; On the left, the responsibilities of the class; On the right, collaborators (other classes) with which the class interacts to fulfill its responsibilities
Tcl allows multiple parent classes; the order of specification in the class declaration affects the name resolution for members using the C3 linearization algorithm. [12] Languages that allow only single inheritance, where a class can only derive from one base class, do not have the diamond problem. The reason for this is that such languages ...
This class does NOT conform to the active object pattern. class MyClass { private double val = 0.0 ; void doSomething () { val = 1.0 ; } void doSomethingElse () { val = 2.0 ; } } The class is dangerous in a multithreading scenario because both methods can be called simultaneously, so the value of val (which is not atomic—it's updated in ...
Finally, introduce a class named Object with members to control its visibility (using a VisibilityDelegate), movability (using an UpdateDelegate), and solidity (using a CollisionDelegate). This class has methods which delegate to its members, e.g. update() simply calls a method on the UpdateDelegate:
Inserting a leading (back)slash, as in "./name", will stop the searching of the path. This is a partially qualified name, but not a fully qualified name as it still depends on the current directory. A fully qualified name, because it contains (back)slashes, will always stop a path search.
Object pooling requires resources – memory and possibly other resources, such as network sockets, and thus it is preferable that the number of instances in use at any one time is low, but this is not required. The pooled object is obtained in predictable time when creation of the new objects (especially over network) may take variable time.
